IMPROVEMENT IN CLOVER THRASHING AND HULLING MACHINES.

Specification forming part of Letters Patent No. 193.786, dated July 31,1877 application filed May 24, 1877.

Cleveland and the latter of Mansfield, in the county of Richland andState of Ohio, have invented certain new and useful Improvements inThrashing'and Olover-Hulhng Machines; and we do hereby declare thefollow ing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and. use it, reference being bad to the accompanying drawings,which form part of this specification.

Our invention relates to a combined grainthrasher and clover-huller; andconsists in certain improvements, fully described and claimedhereinafter.

In the drawing, Figure 1 represents alongitudiual and vertical sectionof a machine embodying our invention. Figs. 2 and 3 repsent oppositeside views of the same. Fig. 4 is a rear-end view. Fig. 5 shows a topview of the separator. Fig. 6 is a front-end view. Fig. 7 is a detachedview of the cylinder.

The device herein described is an improvement on the machine for whichLetters Patent No. 182,318, dated September 19, 1876, were granted tous.

A is a suitable frame, to which the various parts of the machine areattached. B is the thrashing-cylinder. It is provided with a series ofcollars or elevations, b, which may be of any suitable size or form. Thesides of the collars may be inclined, as shown in the drawing, or theymay be at right angles to the main surface of the cylinder. There may bea greater or less number of collars, and their distance from each othermay vary. The surface of the cylinders and collars is corrugated orroughened to a greater or less extent. The cylinder is, preferably,constructed in sections, so that ifany part is worn out it can be easilyreplaced. It may, however, be formed of one piece. Said cylinder isjournaled in the frame 0, which is'vertically adjustable D is theconcave, provided with teeth d. It is secured on each side in a slot ofthe swinging arms (I. Said swinging arms are pivoted at d to the frame0, and are further provided with slots d and d for the insertion of thereceiving-plate 61 The swinging arms may have any number of slots, sothat the receiving-plate can be placed in any desired position. Eachswinging arm [15 also carries a segmental rack, (2 which gears with apinion, (P, on the shaft 01 By turning the crank d in the properdirection the concave may be adjusted nearer to or farther from thethrashing-cylinder, as the revolution of the pinion d operates to effectsaid result. By this arrangement the operation of this portion of themachine can be regulated, and the cleaning of the parts, in case theybecome foul, is facilitated.

F F are two rollers journaled in the frame 0 over thethrashing-cylinder. Around them passes the endless-apron feeder, whichconsists of the endless apron f, upon which are secured the slats orbars f, carrying the teeth f The teeth of the feeder extend or passbetween the sides of the collars on the cylinder when the machine is inoperation. They are, preferably, roughened on their surfaces.

The machine is operated by power applied to the shaft of the cylinder,and it may be transmitted from thence to the feeder by means ofbelt-and-pulley gearing, or in any other suitable and well-known manner.The feeder revolves in an opposite direction from,

and at a lower rate of speed than, the cylin-.

der, for the purpose of effecting the necessary amount of friction orrubbing action to feed the machine, and to feed and head and hull theclover.

E is the feeding-board. To the side pieces of the frame 0 are attachedthe racks G, one on each side. A pinion, g, on the shaft 9 engages witheach rack, and by turning the handle 9 on said shaft in the properdirection the whole frame 0, in which the cylinder and feeder-rollersare journaled, and to which the concave and its adjusting mechanism areattached, is elevated or depressed, as may be required. The slot 9 inthe main frame of the machine permits the shaft of the concaveadj'ustingmechanism to move in the same when the frame 0 is elevated or lowered.The pawl g and ratchet-wheel g serve to hold the concave in any positionin which it may be placed. Bolts h, or other suitable means,

are provided for holding the frame 0 in position.

When the machine is to be used for clover,

the frame (J, with its contained mechanism, is.

placed in its lowest position, and the cylinder is revolved in such adirection as to be called overshot, the clover being fed to the upperface of the cylinder, and passes between it and the endless-belt feeder,which latter serves the function of a feeder in addition to the functionof a header and huller, its action being similar to that of the lowerconcave.

When used for grain, the frame (J is ele vated, so that the grain can befed to the lower face of the cylinder, and therefore passes between itand the lower concave, the cylinder in this instance revolving, ofcourse, in an opposite direction from the former.

N is the separator, which may consist of two or more sections. Eachsection consists of a frame of suitable material, provided with theslanting plates n, the series of them forming and serving the functionof a rake. They may be placed at any effective angle. Each section alsocarries a shaft or rod, n journaled in each end of the section, whichrod is pro vided with a series of teeth, M, of wood or suitable metal,placed at an angle with the rod. This shaft or rod, with its teeth, maybe called the agitator. These teeth project between the slanting plates,and have an oscillating or vibrating motion, as will be hereinafterdescribed.

Between each two sections is placed a division plate or board,'n' whichprevents the falling through of the straw, and serves as a means for theattachment of guide-pieces a. To the main frame are also attached shortguide-pieces a To the upper end of each section, on each side, areattached short grooved projections a in which the guides a and n fit,whereby the upper end of each section is guided in its movements.

P is a slotted guide-piece, having the dovetail slots pp, running in adiagonal direction, as shown. The upper end of each rod 02 is providedwith a finger or bent projection, 00,

which extends into said slots 19.

R is a crank, bent after passing through frame and before entering thesection, and again bent after passing through and before entering theadjoining section, as shown in the drawings. This crank, therefore,moves one section forward while it moves the adjoining section backward,and depresses the crank end of one while it elevates the other.

A given point in the lower end of each section describes the line of acircle when the machine is in operation. As the sections movelongitudinally the shafts or rods a are oscillated on their axes throughthe medium of the dovetail slots 19 and fingers n which causes theagitators n to vibrate laterally, as indipated in dotted linesin Fig. 5.These described movements of the separator operate to carry forward thestraw and to effect the separation of the grain.

M is the upper shaking-board, situated immediately below the separator,which has a longitudinal reciprocating movement imparted to it from thesame shaft that operates the separator through the medium of, lever m,pivoted to the under side ofthe shaking-board, and connecting'link m thelatter being eccentrically pivoted to a disk on the end of said shaft orcrank-shaft R. The lever m is hinged or pivoted to the frame of themachine at m. Qn this shaking-board the clover which has passed throughthe separator is carried back to the cylinder, and undergoes a secondoperation. Attached to this upper shaking board .ondeck, at s '8 by arms8 s, is the lower or perforated shaking-board S, which is freely pivotedor suspended to each side frame of the machine by rods or straps 8 Itmoves in the same manner and direction as the upper shaking-board, and,as is evident, receives itsmo tion from the same.

Next below the perforated shaking'board is placed the shoe T, whichserves to carry the screens for cleaning, and has a lateral or shakingmotion when the machine is operated.

The teeth of the endless-apron feeder-and concave may be of iron or ofwood, and the apron may be of leather or cloth.

The separator may be constructed oftiron or of wood, or both materialsmay be employed.
